K-5 AF.S / AF.C / MF switch defective?

Hi all,

I am new to this great forum and have recently bought a new K-5 with the DA 18-55 AL WR kit zoom.

I noticed that the AF.S / AF.C / MF switch does not have three firm positions, but only has a slight click/stop for each position. Because of this it is easy to put the switch in between the three positions when I have my eye to the viewfinder.

Is this how the switch should function or is the switch on my K-5 defective? I could not find the answer using the search function.

Yep, mine is like that as well. Although... it is kinda hard to switch for me so I can't see how it would get accidentally changed

Mine is the same. There is slight detent on each of the settings but it is not firm. One thing I did notice is that the detents seem to be more noticable going from AFS to AFC to M than they do going from M to AFC to AFS. However it isn't a big issue for me as I rarely shoot in AFC, so I usually just push the lever all the way up or all the way down.

Thanks for the reassurance. I do think that the switch is a bit flimsy regarding its use. However this does not seem to warrant returning the camera. I wonder if other members have a different experience.

It's the Pentax weather sealing effect I guess. If you use your index finger to change it---while shooting--- it's easy enough to feel the AFC position click in. AFS & MF are at the ends so no problem.
This switch does break in nicely if you help it ---Cycle it multiple times enough and it will improve---

The weather seals make it feel "mushy". Not sure why you would consider the lever flimsy, I have not heard of one breaking.

Same here. Hasn't caused any problem.

Mine is the same - I wouldn't describe that as "flimsy", it actually feels too firm to move if anything.
